Hintz Substation - 138 kV Electrical Substation in the United States

Hintz Substation is an electrical substation located in the United States, owned and operated by American Transmission Company. The facility operates at a voltage of 138 kV, placing it within the sub-transmission voltage range typical for regional power distribution and grid interconnection. As part of the broader North American power grid, the substation plays a role in stepping down transmission voltages for local distribution or interconnecting generation sources. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which enforce reliability standards for bulk power systems. The 138 kV voltage level is common for sub-transmission networks that serve industrial, commercial, and residential loads. The facility's location in Wisconsin, with coordinates 44.417643, -88.718337, suggests a rural or suburban setting, typical for substations that support regional grid stability. Environmental considerations for substations include electromagnetic field (EMF) management, oil containment for transformers, and vegetation management to maintain clearance. Hintz Substation, as part of the American Transmission Company's network, contributes to the reliable delivery of electricity across the Midwest, supporting local communities and economic activities. Its operational status ensures continued service to the regional power grid.

The substation is located in a region with mixed agricultural and residential land use, typical of rural Wisconsin. The 138 kV voltage level indicates moderate electromagnetic field emissions, which are managed through standard siting and shielding practices. The facility's operation involves minimal direct environmental impact, with primary concerns being stormwater runoff and vegetation management to prevent outages.
